Today is the last day to file your federal income taxes, or file for an extension. Iowa state tax returns need to be postmarked by April 30.

Iowa PIRG has a petition you can sign on closing corporate tax loopholes, and a trivia question. Of the following 10 companies, which is the only one that has not set up an offshore subsidiary to avoid paying taxes?

* AIG

* American Express

* Bank of America

* Comcast

* Coca-Cola

* Dell

* Exxon-Mobil

* Home Depot

* Pepsi

* Pfizer

Click here for the answer. At that page I also learned that “In all, 83 of the 100 biggest corporations in America have set up off-shore tax shelters, costing the rest of us as much as $100 billion a year!”

The blogosphere is full of funny commentaries on the Republican astroturf campaign to hold “tea parties.” By “astroturf” I mean fake grassroots, organized by conservative interest groups and egged on by their allies at Fox News.

At Daily Kos, KingOneEye has the White House response to the “teabagging” efforts (excerpt):

I think the President will use tomorrow as a day to have an event here at the White House to signal the important steps in the economic recovery and reinvestment plan that cut taxes for 95 percent of working families in America, just as the President proposed doing; cuts in taxes and tax credits for the creation of clean energy jobs.

We’ll use tomorrow to highlight individual and instances in families that have seen their taxes cut and I think America can be — Americans will see more money in their pockets as a direct result of the Making Work Pay tax cut that the President both campaigned on and passed through Congress.

I’m with clammyc: The teabaggers should give up the services their taxes pay for if they believe we get nothing of value in return for our taxes.

Bonddad wants to know, Where were the teabag protests 8 years ago? Good question.

At Open Left, Chris Bowers cites recent Gallup polling, which shows that a solid majority of Americans think upper-income people pay less than their fair share in taxes.

It’s hard to know what’s going on with the Democratic proposal to overhaul Iowa’s tax system. Yesterday key lawmakers predicted it will pass this week, but the Des Moines Register quotes some Democratic back-benchers in the Iowa House today as saying the plan may be dead for this year. I hope we don’t need to add this to the list of good bills we can’t find 51 votes for out of our 56-member Iowa House Democratic caucus.

I haven’t been posting enough open threads lately, so say whatever’s on your mind in this thread–it doesn’t have to be related to tax policy.

UPDATE: I enjoyed Todd Beeton’s Tea Party Palooza linkfest.
